[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and equipment used are all conventional commercial products unless otherwise specified.

[0029] like Figure 1 As shown, the present invention provides a spacer placement device for mines, including a base 10, the base 10 is rectangular, and leveling feet 11 are arranged at the four corners of the base 10, and the leveling feet 11 include a screw sleeve 1102 that passes through the base 10 and is fixedly connected, and a screw 1101 is arranged in the screw sleeve 1102, and the bottom end of the screw 1101 is fixedly connected to a chassis 1104, and the top end is fixedly connected to a screw rod 1103, which is used to drive the screw 1101 to rotate and change the length of the leveling foot 11. A level meter 30 is also arranged on the surface of the base 10, and the level meter 30 is balanced by changing the height of each leveling foot 11, so that the whole device is in a horizontal state.

[0030] The short side of the base 10 is fixedly connected with a column 12, and the top of the column 12 is fixedly connected with a top plate 13. A sleeve rod 15 is provided at the center of the top plate 13, and a delivery rod 14 is sleeved inside the sleeve rod 15. A stepper motor 16 is provided at the top of the delivery rod 14. The output shaft of the stepper motor 16 passes through the top plate 13 and is in transmission connection with the sleeve rod 15. The stepper motor 16 can be used to more accurately control the delivery depth. Fig.15 As shown, the output shaft bottom end of the stepper motor 16 is fixedly connected with a transmission disc 38, the inner wall of the sleeve rod 15 is provided with a transmission groove 39 matched with the transmission disc 38, and a bearing is provided between the transmission disc 38 and the sleeve rod 15, so that the stepper motor 16 can drive the sleeve rod 15 to move up and down while the sleeve rod 15 itself can rotate freely. The surface of the sleeve rod 15 is also provided with a scale to display the placement depth.

[0031] like Fig.14 As shown, a lifting rod 31 is fixed to the top of the delivery rod 14, and a lifting groove 32 is also provided on the side wall of the sleeve rod 15, and the lifting rod 31 extends out from the lifting groove 32. The bottom end of the delivery rod 14 is fixedly connected with a hook 17, and a spacer is hung on the hook 17.

[0032] Example 1

[0033] like Figure 2 As shown, the spacer includes a fixing assembly and a containing bag 23. The containing bag 23 is made of waterproof material, which can not only hold liquid explosives but also isolate the humid environment of the blasthole. Both the fixing assembly and the containing bag 23 are provided with threading holes 24, and the two are connected by hanging with ropes. Figure 3 As shown, the fixing assembly includes a support plate 19, a through hole is provided at the center of the support plate 19, and an anti-drop buckle 18 is provided in the through hole. The anti-drop buckle 18 includes a connecting rod 1802, and the connecting rod 1802 is located in the through hole; the top of the connecting rod 1802 is fixedly connected to an upper lifting ring 1801, and the bottom end is fixedly connected to a limiting plate 1803, the diameter of the limiting plate 1803 is larger than the diameter of the through hole, and a lower lifting ring 1804 is fixedly connected to the bottom wall of the limiting plate 1803. The upper lifting ring 1801 is hung on the hook 17, and the lower lifting ring 1804 is connected to the containing bag 23 through a traction rope 33.

[0034] The support plate 19 and the sleeve rod 15 are also provided with matching limiting components, which are used to maintain the fixed connection between the sleeve rod 15 and the support plate 19 when the upper lifting ring 1801 is pulled off. Figure 3 As shown in Figure 4, the limiting assembly includes a limiting ring 36 fixedly connected to the periphery of the through hole and two limiting blocks 35 fixedly connected to the lower inner side wall of the sleeve rod 15 and arranged opposite to each other. A right-angle groove 37 cooperating with the two limiting blocks 35 is opened on the outer wall of the limiting ring 36. In the process of the sleeve rod 15 being sleeved on the limiting ring 36, the limiting block 35 first enters along the vertical groove of the right-angle groove 37, and then the sleeve rod 15 is rotated to make the limiting block 35 enter the horizontal groove of the right-angle groove 37, completing the limiting of the sleeve rod 15 and the support plate 19 in the vertical direction, so that the relative position of the sleeve rod 15 and the support plate 19 in the vertical direction does not change, providing support for the subsequent tearing operation of the upper hanging ring 1801, and preventing the support plate 19 and the containing bag 23 from falling at the same time.

[0035] The fixing assembly also includes slots 22 arranged in an array around the support plate 19, the slots 22 passing through the side and upper and lower surfaces of the support plate 19, each slot 22 is provided with an expansion claw 20 with the top tilted inward, and the middle of the expansion claw 20 is connected to the support plate 19 via a rotating shaft. Figure 2As shown in FIG. 5 , a threading hole 24 is provided at the top of the expansion claw 20, and the top of the expansion claw 20 is secondarily connected to the receiving bag 23 through a control rope 34, and the length of the traction rope 33 is shorter than that of the control rope 34, so that the receiving bag 23 is only subjected to the pulling force of the traction rope 33 during the delivery process.

[0036] like Figure 6 As shown, the bottom end of the expansion claw 20 is provided with an anti-skid component 21, which is a spike 2103 extending horizontally outward. After the upper lifting ring 1801 is broken, the expansion claw 20 expands outward and the spike 2103 is inserted into the wall of the blast hole, so that the spacer is fixed in the blast hole.

[0037] When in use, the spacer is first placed directly above the blast hole, and the limit block 35 of the sleeve rod 15 is placed in the horizontal groove of the right-angle groove 37; the stepper motor 16 is extended to drop the spacer into the blast hole, and the required depth of the spacer into the blast hole is known according to the scale on the sleeve rod 15; during the dropping process, the traction rope 33 is always in a taut state, and the control rope 34 is always in a loose state. Then the lifting rod 31 is lifted up with force to tear off the upper ring 1801 of the anti-trip buckle 18, and the receiving bag 23 loses the pulling force of the traction rope 33 and falls downward due to its own weight, and the control rope 34 is tightened, and the expansion claw 20 is pulled by the control rope 34 and rotates clockwise, and the bottom of the expansion claw 20 expands outward, and the spike 2103 is inserted flat into the side wall of the blast hole, so that the spacer is fixed inside the blast hole. Then, the sleeve rod 15 is rotated to make the limit block 35 disengage from the vertical groove of the right-angle groove 37, and the stepper motor 16 is shortened to remove the sleeve rod 15 and the delivery rod 14 from the blast hole. Finally, the blast hole is backfilled, and the top of the expansion claw 20 moves downward further under the pressure of the backfill, and the bottom of the expansion claw 20 expands outward further, thereby providing a greater supporting force when it is fixed in the blast hole.

[0038] Example 2

[0039] like Figure 7 As shown, the difference from Example 1 is that the anti-slip component 21 is a spike 2103 extending horizontally downward, which can make the spacer become stronger and stronger after being inserted obliquely downward into the inner wall of the blasthole due to its own weight and the backfilling of the blasthole.

[0040] Example 3

[0041] like Figure 3 As shown, the difference from Example 1 is that the anti-slip component 21 includes a bonding plate 2101, the bonding plate 2101 is hinged to the expansion claw 20, and the outer surface of the bonding plate 2101 is provided with a ratchet 2102, and the ratchet 2102 is stepped, so that when the bonding plate 2101 is bonded to the inner wall of the blast hole, the inner wall of the blast hole is squeezed by the bonding plate 2101 to form a shape that matches the ratchet 2102, and is fixed by overlapping.

[0042] Example 4

[0043] like Figure 8 As shown, the difference from the embodiment 1 is that each notch 22 is provided with an expansion claw 20 with the top tilted outward, and the bottom of the expansion claw 20 is connected to the support plate 19 through a rotating shaft. The top of the expansion claw 20 is provided with a spike 2103 extending horizontally outward.

[0044] When in use, after the upper hoisting ring 1801 is broken, the control rope 34 is tightened to pull the expansion claw 20 to rotate counterclockwise, so that the ratchet 2102 is inserted into the inner wall of the blast hole.

[0045] Example 5

[0046] like Fig. 9 As shown, the difference from the fourth embodiment is that the top of the expansion claw 20 is provided with a spike 2103 extending horizontally downward.

[0047] Example 6

[0048] like Fig.10 , as shown in FIG11 , the difference from Example 3 is that the notch 22 only passes through the upper and lower surfaces of the support plate 19, and an expansion slot 25 connected to the notch 22 is provided on the side wall of the support plate 19, and a push block 26 is slidably arranged in the expansion slot 25, and the outer end of the push block 26 is fixedly connected to the bonding plate 2101. The bottom end of the expansion claw 20 is arranged opposite to the push block 26, so that when the expansion claw 20 is pulled by the control rope 34 and rotates clockwise, the bottom end of the expansion claw 20 can push the push block 26 outward to move, thereby making the bonding plate 2101 bonded to the inner wall of the blasthole.

[0049] Example 7

[0050] like Fig.12 As shown in FIG. 13 , the support plate 19 is eliminated in this embodiment. A telescopic sleeve 40 is additionally sleeved on the connecting rod 1802 of the anti-drop buckle 18. The fixing assembly includes four transverse rods 27 fixed on the telescopic sleeve 40 in an array. The top surfaces of the four transverse rods 27 are fixedly connected with a limiting ring 36. An expansion rod 28 is sleeved on the transverse rod 27. The outer end of the expansion rod 28 is fixedly connected with a bonding plate 2101. A connecting shaft 29 is fixedly connected to the side wall of each transverse rod 27. An expansion claw 20 is rotatably matched with the connecting shaft 29. The material of the limiting plate 1803 is more fragile than the upper lifting ring 1801, so that when the lifting rod 31 is lifted with force, the limiting plate 1803 is torn and damaged first, so that the traction rope 33 loses the pulling force on the accommodation bag 23; then the control rope 34 is tightened to drive the expansion claw 20 to rotate clockwise, and the bottom end of the expansion claw 20 directly pushes the bonding plate 2101 to expand outward, thereby fixing the spacer in the blast hole.
